Title: Concave mirror lighting unit
IPC: F21V5/00
Filed: 1981-10-30
Abstract: The invention relates to a concave mirror lighting unit having a concave mirror reflector with at least one luminous element which is arranged in the focal region of the concave mirror reflector, and further optical means which are preferably arranged in the cover plate of the concave mirror reflector. Concave mirror lighting units are frequently used as headlamps on vehicles. In order to increase the illuminance in the intermediate region between the point of incidence of the axial main light bundle on the roadway and the vehicle, there is arranged between the cover plate and the luminous element a collector lens which collects the light emanating forwards from the luminous element. Optical means which deflect the collected light downwards are then arranged in front of this collector lens. Again, the gap between the point of incidence of the axial main light bundle and the vehicle can be better lit up by arranging in the region of the light bundle collected by the concave mirror reflector special optical means which deflect downwards and direct a portion of the axial light bundle into said gap.

Patent DE-3149589-A1 (DE)
Title: Rope drum for a rope winch of a hoisting machine
Inventor: FENZL FRANZ ING GRAD
IPC: B66D1/30
Filed: 1981-12-15
Abstract: The invention deals with a rope drum construction which enables any run-on and run-off speed between 0 and a maximum speed as well as constant or variable starting acceleration or run-off retardation to be obtained in the simplest manner and at constant angular velocity. This result is achieved by staggering the centres of rotation of various rope-drum parts or individual sheaves. Normally, starting speeds of 0, on account of the regulation that the smallest rope-layer diameter is to exceed 10 times the rope diameter, cannot be reached in normal stepped drums. The invention shows ways in which the movement can start at zero speed by eccentric staggering E of the run-on and run-off part (1, 3) relative to the main part (2) of the rope drum while maintaining the 10d regulation. By the use of an Archimedean, logarithmic or hyperbolic spiral between eccentric initial rope layer and rope layer for maximum speed, any run-on or run-off characteristic from 0 is possible. Details relate to embodiments of rope drums of this type. <IMAGE>

Title: Angled mirror
IPC: G02B7/18
Filed: 1982-02-15
Abstract: The aim is for an angled mirror, consisting of a plastic core, which has end glasses arranged on an outward-looking side and on an inward-looking side, as well as deflecting mirrors provided on two deflecting surfaces, to be improved in order effectively to prevent the penetration of moisture and/or solvents into the plastic core.

The coating (17) preferably consists of a metal foil, in particular an aluminium foil. In order to increase reliability with respect to the undesired penetration of moisture and/or solvents, it is provided to cover the joints or circumferential edges in the transition region between the end glasses (14) and the deflecting mirrors (16) and the plastic core (11) with an additional layer which consists of a material impervious to moisture and solvent, or at least of a material which diminishes the perviousness to moisture and solvent. <IMAGE>

Title: Device for accommodating oscillator crystals
Inventor: FAIST EUGEN ING GRAD
IPC: H03H3/04

Abstract: The invention relates to a device for accommodating oscillator crystals, particularly crystal oscillators, for multiple calibration, preferably the multiple calibration in which the connecting wires of the crystals must be contacted during the calibration process and preferably several such crystals are combined in a transportation group. In such devices, connecting wires suitable for this purpose must be contacted during the calibration process. According to the invention, this object is achieved by the fact that a helical spring (11) presses, with the aid of an associated drive such as, for example, a pinion wheel (14) and a rack, the connecting wires (2) to be contacted against the surfaces of such holes (8) which are provided in contact pins (9) and can be connected to associated electrical signal sources during the calibration process. <IMAGE>

Filed: 1982-07-15
Abstract: In a chain lock for link chains, a locking arrangement, to which a preassembled unit consisting of a retaining element (1) and of a spreading element (5) belongs, is used. The spreading element (5) has an essentially oval initial shape in the unspread state. It can be introduced by hand into the region of catch recesses (8) of the inner legs (6, 7) of lock halves of the chain lock. A locking of the lock halves is obtained by the rotation of the spreading element (5) in the region of the catch recesses (8). The spreading element (5) pivoted through 90 DEG  can subsequently be transferred by means of a hammer into its end position, in which it is supported on a cylindrical catch part (3) of the retaining element (1). <IMAGE>

Title: Counter
Inventor: KUEBLER FRITZ ING GRAD
IPC: G06M1/32
Filed: 1982-10-09
Abstract: For the purpose of resetting, the counter is provided with a resetting device which is a resetting key separate from the counter. It is provided with a slide for displacing the axis of the switch drive of the counter, and with a grip part on which the slide and the fingers are provided with which the number drums can be reset to zero. As a consequence of the separate resetting key, the counter has a simple structural design and can be produced simply and cost- effectively. Furthermore, as a result the counter can be built very small. Since all the fingers for the number drums are provided on the resetting key, all the number drums of the counter can be set to zero simultaneously, so that resetting is possible simply and rapidly.

Title: Latching mechanism for pivotable rear-seat backrests of motor vehicles
Inventor: BOETTCHER CURD DIPL ING
IPC: B60N2/36
Filed: 1983-04-02
Abstract: A latching mechanism for pivotable rear-seat backrests of motor vehicles has latching elements arranged on the vehicle-body interior wall on both sides of the backrest and associated locks which are attached to both sides of the backrest and have manually actuable locking elements which cooperate with the latching elements. The locking elements are in each case formed by one end of a lever mounted pivotably against spring resistance in a lock housing. When the latching element is subjected to tensile loading directed in the direction of travel, the locking element forms a common stop together with the lock housing wall which faces the latching element. The locking element is arranged in the lock housing behind a passage opening in such a manner that it comes to rest in the locking position inside on the lock housing wall facing the latching element. At its free end cooperating with the locking element, the latching element is designed in the manner of a "T" with a T-crossbar angled or bent downwards asymmetrically towards one side, that part of the T-crossbar of the latching element which is directed rearwards reaching behind the locking element in the locking position in the manner of a hook. The aforementioned latching mechanism has the essential advantages of being capable of being produced in a simple, space-saving and cost-saving manner without using high-quality materials. It can be subjected to extremely high loads, as a result of which also in ... Original abstract incomplete.
